MAS Biaxial Fiberglass Cloth requires a low amount of resin and features the ability to lay fiber in any direction. It provides heavy-duty reinforcement that's common in marine construction and is useful where high strength and fast buildup are necessary such as in repairs and tabbing. It conforms to your desired shape easily and is stitched at a 45° angle with a 3/4-oz. mat backing, which results in a smoother finished look. Mat in the fabric is fully compatible with polyester, vinyl, and epoxy resins.
